Input Power
•
DC Input: This charger can be powered by a portable 12V DC power source for use at
the field/track. On the left side of the charger, connect the DC power cord’s alligator
clips directly to the output terminals on the 12V DC power source.Always match
polarities (red lead to red ‘ +’ terminal, black lead to black ‘ -’ terminal). To utilise the
charger’s absolute maximum power capabilities the DC power source must be capable
of delivering at least 5 amps while maintaining 12 volts DC.
WARNING! Never accidentally short together the positive (+) and negative (-) input
connections when connected to the 12V DC power. Doing so could result in permanent
damage to the power source and the charger.
This charger is rated for a maximum output power of 45 watts. Depending on certain
conditions (if the charge current is set to maximum, the maximum number of cells are
connected to the output, and input voltage is low), the actual current delivered to the
battery might be slightly less than the setting. This is normal.
The charger will be on all times when connected to input power. Disconnect the charger
from input power when not in use.

Charging Guidelines
Nominal Voltage level: 1.2V/cell.
Recommended fast charge current: 1C-2C, depending on the
performance of the cell. Higher discharge batteries can charge at 2C.
x
C = ÷ 1000 (Where x= Battery capacity eg: 2200mAh).
Lilon (Lithium Ion)
Nominal Voltage level: 3.6V/cell
Max. charge voltage: 4.1V/cell
Recommended fast charge current: 1C or less (0.5C recommended).
LiPo (Lithium Polymer)
Nominal Voltage level: 3.7V/cell
Max. charge voltage: 4.2V/cell
Recommended fast charge current: 1C or less. Some of the very latest LiPo cells
can accept 2C charging or more but check with the battery manufacturer first.
If in doubt, never exceed 1C.

Battery Connection
1. For NiCd/NiMH: Plug the adapter into the charger FIRST. Then connect the battery
to the adapter ONLY after it has been connected to the charger.
Proceed to the “Starting Charge” section.
2. For LiPo, Li-Ion or LiFe: Lithium batteries for R/C are commonly available in two
different assembly/wiring configurations: wired for balancing and non-balanced.
It’s important to know which configuaration you have before proceeding.
Consult your battery supplier if you are unsure if your battery is wired for balancing,
if it is not wired for balancing but has a built-in safety circuit, or neither.
WARNING! It is NOT recommended to charge a LiPo battery which is not wired for
balancing. Such types of LiPo have NO means to protect the equipment or the user
from damage that could result from an overcharge condition of any cell in the pack.
NON-BALANCED packs are wired so the charger can only detect the voltage of
the entire pack (not individual cells), so there is only one charge lead. It’s highly
recommended to ONLY use such types of LiPo packs if they have a built-in charge
safety circuit which prevents any single cell in the pack from being overcharged.
Simply connect the battery’s main power lead to the charger’s banana jacks
(noting correct polarity).

Charge Complete
For NiCD and NiMH batteries, a linear charge current will be delivered to the battery.
The peak detection method will be used to accurately look for the highest battery
voltage during charge. Once this is detected, the charger will automatically stop fast
charge and go to trickle charge mode.
CAUTION: Make sure the charge current setting is safe for your battery to prevent
overheating of the cells. ‘AAA’, ‘AA’,’A’ and ‘2/3A’ size batteries generate heat more
quickly than large sub-C batteries. Most radio batteries should NOT be charged at
currents greater than 1.5A. Failure to follow this recommendation could permanently
damage the battery.
Lithium Batteries are charged using the “constant current /constant voltage” method
(CC/CV). Constant current is delivered during the first part of fast charge . When the
battery reaches pre-set voltage, constant current is no longer delivered, and constant
voltage is applied to the battery . As the battery’s voltage becomes equalised to the
voltage on the charger’s output, charge current will steadily begin to drop.
This is normal. When current reaches an approximate value of 1/10C, the charge
process will end completely.
When the charger has determined the battery is full, it will stop the charge process
automatically and show ‘FULL’ on the LCD screen. Audible tones will sound for
about 10 seconds (pressing STOP while the tones are sounding will turn them of f).
Information regarding the finished charge can be recalled by pressing the DISPLA Y
button. Please refer to the flow chart for the data that can be recalled .

DO NOT allow NiMH batteries to overheat (above 50°C)! Disconnect overheated
batteries from the charger immediately and allow to cool.
DO NOT attempt to use the charger’s lithium functions with NiMH batteries and
vice versa.
Store NiMH packs with some voltage remaining on the cells (refer to battery
supplier).
It is important to recharge NiMH batteries immediately prior to use, as they have
a higher self discharge rate.
WARNING! DO NOT try to charge lithium-polymer (LiPo) lithium-ion (Li-Ion) or LiFe
cells in the same way as other battery types! Always read the instructions that are
included with your lithium batteries carefully before use. Failure to follow these
care and handling instructions can quickly result in severe, permanent damage
to the batteries and their surroundings and even start a fire!
ALWAYS charge lithium batteries in a fireproof location, which could be a
container made of metal or ceramic tile. Monitor the area with a smoke or fire
alarm, and have a lithium approved fire extinguisher available at all times.
For NiCd and NiMH batteries, the trickle charge current value is set automatically by the
charger as shown in the chart below and shown in amp “A”. The charger will remain
in trickle charge mode until the battery is disconnected from the charger, or the STOP
button is pressed again.
Trickle charge will NOTbe applied to lithium batteries. When fast charge ends, lithium
batteries can be disconnected from the charger and are ready to use.
If the fast charge 180 minute backup safety timer expires before the battery is fully
charged, the LCD display will show STOP. Should this occur, you might want to attempt
to re-charge the battery by starting another charge. Refer to the Trouble Shooting Guide
on page 14 for more details.
NEVER attempt to extinguish a lithium fire with water or a non-lithium approved
fire extinguisher! Use ONLY a Class D (CO2 or powder) fire extinguisher.
ALWAYS provide adequate ventilation around LiPo/Li-Ion/LiFe batteries during
charge, while in use, and during storage.

NEVER charge LiPo, Li-Ion or LiFe batteries at currents greater than the maximum
rated current as specified by the battery’s manufacturer.
NEVER allow LiPo cells to come into contact with moisture or water at any time.
NEVER allow the electrolyte from LiPo, Li-Ion or LiFe batteries to get in the eyes
or on the skin - wash affected areas immediately if they come in contact with the
electrolyte and contact your doctor.
NEVER attempt to use the charger’s NiCd and NiMH functions for LiPo or Li-Ion
batteries.
ALWAYS keep lithium batteries away from children.
NEVER attempt to charge a lithium battery that is swollen or where one cell is
under 3.0V
NEVER allow LiPo, Li-Ion or LiFe cells to overheat at any time as they can become
physicaly damaged and could possibly explode or catch fire! If a battery becomes
overheated (over 140°F, 60°C), disconnect it from the charger IMMEDIATELY.
NEVER continue to charge LiPo, Li-Ion or LiFe batteries if the charger fails to
recognise a full charge. LiPo and LiFe cells which swell or emit smoke may be in
overcharge condition and should be disconnected from the charger immediately.
NEVER set the charger’s LiPo/Li-Ion or LiFe battery voltage settings to a voltage
that is HIGHER than the nominal rating of the battery itself, as such cells cannot
handle overcharging in any way.
The B405 incorporates various functions to protect and monitor the system,to verify
functions and the state of its electronics . In the case of an error , the screen will
display the cause of the error. This is also warned via an audible sound.
The DC input voltage is below 10.0V or exceeds 18V DC. Make sure
that the input voltage is within this range.
A battery is not connected to the output . Make sure a good connection
exists between the battery and charger and re-try.
